Solve.

3 + j / 11 = 2

j =__________

Answers

j would equal -11
first subtract 3 so 2 is -1
then divide -1 by 11
so j=-11

This is how you solve it:

3 + j / 11 = 2

3 + j = 2 × 11

3 + j = 22

j = 22 - 3

j = 19

Now you could check your answer by substituting the value of j :

3 + j / 11 = 2

3 + 19 / 11 = 2

22/11 = 2

2 = 2

Find the area of the polygon with vertices of A(0,1), B(0,5), C(4,5), and D(6,1).

Answers

If you draw that out on a coordinate grid, you get a trapezoid with one base 6 units long, one base 4 units long and a height of 4. Using the formula for area of a trapezoid

h(b1 + b2)/2

where h is the height, 4, b1 is a base, 6, b2 is the other base, 4, we get

4(4+6)/2

which is 4(10)/2 or 40/2

which gets us the answer, 20

Is anyone good at elimination method? I will give 10 points to the person that answer the question. :)Jill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

Answers

To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.

-3!
-3y=-3x-24
y=3x-11
-2y=-35
y=17.5

Margie hiked a 17 7/8 mile trail.She stopped every 3 2/5 miles to take a picture.Which is the best estimate of the number of times she stopped ? A 4. B 6. C 7. D 8.

Answers

Answer:

Option B is the correct answer

Step-by-step explanation:

Margie hiked a 17 7/8 mile trail.

$\texttt{Distance hiked by Margie = }17(7)/(8)=(17* 8+7)/(8)=(143)/(8)mile$

She stopped every 3 2/5 miles to take a picture.

$\texttt{Distance at which she stopped to take picture = }3(2)/(5)=(3* 5+2)/(5)=(17)/(5)mile$

$\texttt{Number of pictures taken = }\frac{\texttt{Distance hiked by Margie}}{\texttt{Distance at which she stopped to take picture}}\n\n\texttt{Number of pictures taken = }((143)/(8))/((17)/(5))=(715)/(136)=5.28$

So she can take maximum of 6 picture and minimum of 5 picture.

Option B is the correct answer

17 7/8÷3 2/5
143/8÷17/5
multiply by reciprocal
143/8×5/17= 715/136= 5.26 which is closer to
B. 6
